 |
|
I came to possession of a bunch of wafers and I am trying to identify them. As far as I can tell they are all rockwell ones.
This is the text I was able to find on them. Not much more than that.
Signal Processor Exp R5316 48H1111
Rockwell International R5338-1A1 DCP88A PC503A
Rockwell International 10462 11189 DCP83DB
Rockwell internation C1802 11193P
Rockwell internation R1113-1 |

| Pics of whole die are indeed more useful. That would let us identify microcontroller or digital signal processor cores. |
